What was it about

Hey Sulit do you wanna learn about Ruth analysis? How about Root Locuses?


How do you feel about drawing these funny shapes?

Don’t worry Ruth analysis is really easy I’ve actually told may about how it takes 2 minutes

So let’s say we have a s^3 + 2s^2 + 1s + 1 charvatsrsric equation so then we have

s^3 3 1
s^2 2 1
s^1 = -1/2 * (3-2) 0 = -1/2 0
s^0 = 2 (+1/2) = 1

Ruth analysis is actually insanely easy, because, and I quote my professor

it’s mechanically easy once you do it once. it just follows a couple rules

Mmmmmmm

any b uses the value of the first col row above for -1/that value
any b+n uses the first col and first col +n+1 for the determinant

oh yeah if you get all zeros you take the dererative of the polynomial created above that row and also if there’s a zero in the first row you replace it with elpison

and use that to replace the values

oh yeah if yoy get elpison/nymber + number replace the col with elipson/number and get rid of the +, but if it’s elipson swuare you get rid of elipson/number and keep the constant

Why? I don’t fucking know.

I think I’m good

Elpison is just a small number postive or negatife so I assume that it just has something to do with elpison^2 always being postive

It sounds scary but I literally did an example in 2 mins

Engagement farming failed.

Nobody else really cared about it either :wowee:

much like current in a circuit I like taking the path of least resistance (daily schedule that involves the least amount of effort) to ground (my bed) and that seems to take a lot of effort

it’s so fucking easy it’s just three…four…five rules!
